182 Notices of Ewopean Herbaria. 



There is also the very complete Newfoundland collection of La Pylaie, 

 comprising about 300 species, and a set of Berlandier's Texan and 

 Mexican plants, as well as numerous herbaria less directly connected 

 with North American botany, which we have not room to enumerate. 

 Here, however, we do not find the herbaria of several authors, which 

 we should have expected. That of Lamarck, for instance, is in the 

 possession of Professor Roeper at Rostock, on the shores of the Baltic ; 

 that of Poiret belongs to Moquin-Tandon of Toulouse ; that of Bosc, 

 to Professor Moretti of Pavia ; and the proper herbarium of the late 

 Desfontaines, which, however, still remains at Paris, now forms a 

 part of the very large and valuable collections of Mr. Webb. The 

 herbarium of Mr. Webb, although of recent establishment, is only 

 second to that of Baron Delessert ; the two being by far the largest 

 private collections in France, and comprising not only many older 

 herbaria, but also, as far as possible, full sets of the plants of recent 

 collectors. The former contains many of Michaux's plants (derived 

 from the herbarium of Desfontaines), a North American collection, 

 sent by Nuttall to the late Mr. Mercier of Geneva, a full set of Drum- 

 mond's collections in the United States and Texas, etc. I'he latter 

 also comprises many plants of Michaux, derived from Ventenat's 

 herbarium, complete sets of Drummond's collections, etc. But a 

 more important, because original and perhaps complete set of the 

 plants of Michaux, is found in the herbarium of the late Richard, 

 now in the possession of his son. Professor Achille Richard, which 

 even contains a few species that do not exist in the herbaxium at 

 the Royal Museum. The herbarium of the celebrated Jussieu, a 

 fine collection, which is scrupulously preserved in its original state, 

 by his worthy son and successor. Professor Adrien Jussieu, com- 

 prises many North American plants of the older collectors, of which 

 several are authentic for species of Lamarck, Poiret, Cassini, etc. 



The herbarium of DeCandolle at Geneva, accumulated through- 

 out the long and active career of this justly celebrated botanist, and 

 enriched by a great number of correspondents, is surpassed by few 

 others in size, and by none in importance. In order that it may re- 

 main as authentic as possible for his published works, especially the 

 * Prodromus,' no subsequent accessions to families already published 

 are admitted into the general herbarium, but these are arranged in a 

 separate collection. The proper herbarium, therefore, accurately 

 exhibits the materials employed in the preparation of the * Prodro- 

 mus,' at least so far as these were in Professor DeCandolle's owti 

 possession. As almost twenty years have elapsed since the com- 

 mencement of this herculean undertaking, the authentic herbarium 

 is of course much less rich in the earlier than in the later orders. 

 The Compositse, to which seven years of unremitted labour have 

 been devoted, form themselves an herbarium of no inconsiderable 

 size. It is unnecessary to enumerate the contributors to this collec- 

 tion (which indeed would form an extended list), since the author, 

 at least in the later volumes of the ' Prodromus,' carefully indicates, 

 as fully as the work permits, the sources whence his materials have 

 been derived, llie paper employed is of an ordinary kind, some-
